If you’re traveling on a budget and all you need is a clean bed and a roof over your head, then Generator Copenhagen is exactly what you’re looking for.
In the room I stayed in had 6 bunk beds with 11 roommates. Your actions in the room could be very limited if you choose to be considerate to others- people sleep at different times of the day and almost always someone is resting in the room. There is a storage-bin under the bed, and it was just bed enough to fit my carry-on suitcase. Bring your own lock and you’re all set.
There were two showers and one toilet in the room. Service was decent- I didn’t need much service aside from checking-in. There is a bar and cafe within the building- as well as a gaming, outdoor smoking, computer, and hammock area.
This hostel is 7 minute walk from the Nyhavn- very central location. The metro and many bus lines are just minutes away.
Location: Adelgade 5, 1304 København K, Denmark (near Kongens Nytorv metro station)
